Question

what percentage of the shape is blue?
write your answer using a percent sign (%).

Explanation:

Step1: Count total grid cells

The grid is a 10x10 square, so total cells = $10 \times 10 = 100$

Step2: Count blue grid cells

Count the shaded blue cells: $10$

Step3: Calculate percentage

Percentage = $\frac{\text{Blue cells}}{\text{Total cells}} \times 100\% = \frac{10}{100} \times 100\%$

Answer:

10%
